Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended temperature range (-40°C to +85°C) compared to standard variants. Confirm the 18 pF load capacitance matches the host circuit design requirements. Ensure the 2-SMD footprint dimensions align with the PCB layout constraints. Check RoHS compliance status for current regulatory adherence.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required within an industrial or extended commercial temperature environment. The 18 pF load capacitance must be compatible with the oscillator circuit's input capacitance. Consider the 60 ohm ESR limit to ensure proper oscillation startup conditions are met without excessive drive level sensitivity.

Crystals Part Context

This part belongs to the 403 series of glass-sealed crystals from CTS-Frequency Controls. These components are designed for general-purpose timing applications where reliability and stability are critical. The series offers various frequency options and package sizes to accommodate different board space and performance requirements.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz SMD crystals with identical 18 pF load capacitance and ±30 ppm stability. Verify that alternative parts support the -40°C to +85°C temperature range and match the 3.2mm x 2.5mm footprint. Cross-reference ESR specifications to ensure circuit compatibility.
